The largest piston that I have personally put into a SR20 block without boring is 87mm. I have seen a few pistons at 87.5 mm sold by Tomei and other companies, so I am guessing that this size will fit also without sleeving.
The question is has anyone put a 88mm piston in a SR20 motor without sleeving it or maybe even a 88.5 piston?
